Using the given points and line, determine the slope of the line. (1, 2) and (2, 1)
Solution:
The slope of the line passing through two points (x1,y1) and (x2,y2) is given by
\(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)
Now, the slope of the line passing through the points (1,2) and (2,1) is given by
m = (1 - 2) / (2 - 1)
m = (-1) / 1
m = -1
Therefore, the slope of the line is -1.
Example: Using the given points and line, determine the slope of the line. (3, 2) and (2, 3)
Solution:
The slope of the line passing through two points (x1,y1) and (x2,y2) is given by
\(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)
Now, the slope of the line passing through the points (3,2) and (2,3) is given by
m = (3 - 2) / (2 - 3)
m = 1 / (-1)
m = -1
Therefore, the slope of the line is -1.
Using the given points and line, determine the slope of the line. (1, 2) and (2, 1)
Summary:
The slope of a line that passes through the points (1,2) and (2,1) is -1.
